9p: treat read return values of 0 as EOF
If your 9p server shares a synthetic file system such as sysfs, the file
size from stat often disagrees with the actual file size.
Treat non-error reads of 0 as EOF, except in the case where the request
was for 0 bytes.
Tested:
git@github.com:hugelgupf/p9.git, served "/" on 10.0.2.2
bash-5.3# mount -t 9p -o trans=tcp,port=12345,cache=none 10.0.2.2 /tmp/foo
bash-5.3# cat /tmp/foo/sys/devices/system/cpu/online
0-47
